Japanese music video director Tetsuro Takeuchi applies his talents to this edgy, fast-paced, dizzying film about Ace (Masashi Endô), a young man who worships the popular Guitar Wolf (played by the real-life members of a group sporting the same name). After witnessing the band about to be double-crossed by a club owner, Ace helps them seek revenge. Impressed, Guitar Wolf's leader proclaims him a radical hero, a title Ace takes to the hilt.
